Despite studies indicating that the vitamin D intake among Swedish children and adolescents are significantly below recommendations, little is known of their vitamin D status (Garemo et al, 2007, Enghardt et al, 2006, Öhlund et al, 2010). Furthermore there is a paucity of studies investigating vitamin D intake and status in food-allergic adolescents who may be at increased risk of vitamin D insufficiency due to strict avoidance of vitamin D containing foods.
